A survey of muskrat pushups was conducted in spring 2013 along the Slave River
from just north of Fort Chipewyan to Great Slave Lake. Densities and abundance
of pushups were highest in the Slave River Delta, where wetlands provide good
muskrat habitat. The survey provides a baseline of information that can be compared
to future surveys, and enables environmental change to be tracked over time.
The NWT Environmental Research Bulletins (NERB) are series of brief plain language summaries of various environmental research findings in the Northwest Territories. If you’re conducting environmental research in the NWT, consider sharing your information with northern residents in a bulletin. These research summaries are also of use to northern resource decision-makers.

Muskrat pushup abundance along the Slave River
This project was a Slave River and Delta Partnership1 (SRDP) led initiative, a collaboration of many partners. The SRDP also collaborated with the Peace-Athabasca Delta Ecological Monitoring Program and Parks Canada who were undertaking a survey of the Peace-Athabasca Delta and Alberta stem of the
Slave River.
